DEVICE FOR TRANSMITTING POWER.

SPECIFICATION forming part of Letters Patent No. 592,435, dated October 26, 1897.

Application filed November 27, 1896. serial No. 618,627. (No model.)

' To aZZ whom it may concern; B is another shaft or axle held transversely Be it known that 1, FRANK J. NOECHEL, of at or near the other end of the frame to be Rochester, in the county of Monroe and State operated by the driving-crank H. The axes 5 of New York, have invented a new and useof the shafts or axles O and B are parallel 5 f ullmproveinent in Devices for Transmitting and in the same plane.

By means of the sliding head G and the Referring to the figures, A is a metal frame pivot-pin f, joining it With the connector Fat for supporting the other parts, it being comthe middle of the latter, the middle part of posed of a long member d and a short memthe connector is controlled and held to move too her 0, held side by side by simple fasteners backward and forward in a right line between A rotary driving shaft or axle C is held transthe eccentric bearings D and E; but the versely at one end of the frame, provided with ends of the connector turn in circles during an operating-crank H. the operation of the parts. This pivotal motion of the connector effectually prevents the occurrence of what is known as dead-centers, which usually attend machines in which rotary and reciprocal parts join.

\Vhen the driving-crank His horizontal, as shown in Fig. 1, and the parts are all in line, the connector F will act momentarily purely as a lever of the first order if the crank is carried downward, but this lever action of the connector will decline as the crank moves downward until the latter stands vertically downward, as shown by dotted lines. IVhen this position of the crank is reached, the connector no longer acts as a lever, but acts to deliver a direct endwise push or thrust against the bearing D; but as the crank moves onward the thrust pressure or action of the connector immediately commences to decline and wholly disappears when the crank comes again in. line with the other parts with its free end directed toward the axle B. At this time the connector again acts as a lever of the first order, which characteristic Wholly disappears again when the crank assumes a vertical upward position. At this point the action of the connector is to exert for a moment a direct endwise pull upon the bearing D, which pull declines as the crank moves onward, and

disappears wholly when the crank reaches its original horizontal position. (Shown in full lines in Fig. 1.) That is to say, at the beginning of the first quarter of a revolution the connector acts as a lever, at the beginning of the second quarter it acts to deliver a direct push, at the beginning of the third quarter it again acts as a lever, and at the beginning of the fourth quarter it exerts a direct pull. In every case, when the crank moves from the beginning of any quarter of a revolution to the beginning of the next succeeding quarter the particular action of the connector at the former quarter will gradually merge into the particular action of the connector incident to the latter quarter. From this description it will be seen that there is no point in a complete revolution of the driver in which a dead-center can occur. The action of the driver upon the driven part is continuoulsy effectual throughout a complete revolution. The pivotal action of the connectorthat is to say, its action as a leverat the two points in a revolution where dead-centers only could occur effectually prevents their occurrence. It is of course not essential how or by what means the driveris turned, whether by a crank, gearing, or other means, and it is also evident that any device may be connected with the driven axle, according to the use to which the device may be put or the work to,

be done. As shown, a spur-gear I is made rigid with the bearing D. Also a pinion K is shown in mesh with the gear, the pinion being rigid with the shaft-L, which may be, for example, the axle of the rear wheel of a bicycle, the crank II serving as a pedal-crank for the Vehicle. In this use the upturned part Nof the frame corresponds with the rear fork of the bicycle, and the ordinary sprocket wheels and chain are dispensed with.

The antifriction-balls i are introduced into the ball-races r of the bearings through openings in the end pieces 9 and h, one of which openings is shown at 1), Fig.1. The openings communicate with the respective races, and when the end pieces are secured to the main part of the connector said openings are closed by the presence of the main part so the balls cannot escape.

I claim- 1. In a device for transmitting power, the combination, with a twopart frame, the central portion of which is provided with parallel parts, and one of the parts of the frame is longer than the other, of a shaft journaled at each end of the frame, an eccentric upon each shaft, a head upon the parallel portion of the frame, and a connector pivotally secured to the head and having its ends connected with the eccentrics, substantially as set forth. v

2. In a device for transmitting power, the combination, with a two-part frame, the longer part of which isprovided at one end with a projection, and the end of the shorter part is secured thereto, a shaft journaled at each end of the frame, an eccentric upon each shaft, a head upon the frame, a connector pivotally secured to the head and having-its ends connected with the eccentrics, substantially as set forth.

3. In a device for transmitting power, the combination, with a two-part frame, the central portion of which is provided with a parallel portion, of a shaft at each end of the frame provided with an eccentric, a two-part head between the parts of the frame, each part of which is'provided with means for engaging with the parallel portions of the frame, a pin in the head, an open frame-connector provided with a cross-bar pivotally secured upon the pin, the ends of the connector being connected with the eccentrics, substantially as set forth.

4. In a device for transmitting power, the combination, with a frame, of a shaft journaled at each end thereof, an eccentric upon each shaft, a head upon the central portion of the frame, a connector pivotally secured to the head and having its ends connected with the eccentrics, each end of the connector having an openingleading into the space between the eccentrics and the connectors, and balls within the space, substantially as set forth.

In witness whereof I have hereunto set my hand this 24th day of November, 1896, in the presence of two subscribing witnesses.
